INTRODUCTIONThis book contains all the necessary fitting and operating instructions for your Alterna Florino thermostatic mixer shower.

Please read these instructions carefully. Read through the whole of this book beFORe beginning your installation.

The shower installation MuST be carried out by a suitably competent person and in sequence of this instruction book.

Care taken during the installation will provide a long and trouble free life from your shower.

For the best performance within the specified running pressure range a minimum flow of eight litres per minute should be available to both inlets.

This mixer is designed to operate on higher pressure systems found in the uK up to a maximum of 5 bar running pressure. The valve MuST nOT be subjected to water temperatures above 80°C.

This mixer is suitable for fully modulating type combination boilers and multi-point hot water heaters. It is also suitable for thermal storage, unvented systems and pumped gravity systems.

Important: Before installing with a gas instantaneous water heater, make sure it is capable of delivering hot water at a minimum switch-on flow rate of 3 litres per minute. At flow rates between 3 and 8 litres per minute, the appliance must be capable of raising the water temperature to a minimum of 52°C. The water temperature at the inlet to the mixer must remain relatively constant when flow rate adjustments are made (refer to the water heater operating manual to confirm compatibility with this mixer shower).

Inlet connections are to 15 mm compression or ½” bSP female fittings (not supplied).

SAFETY WARNINGSa. Layout and sizing of pipework MuST be such

that when other services are used, pressures at the shower control inlets do not fall below the recommended minimum.

b. DO nOT choose a position where the shower could become frozen.

c. DO nOT connect this mixer shower to any form of tap or fitting not recommended by the manufacturer.

d. The showerhead MuST be regularly cleaned to remove scale and debris.

e. Conveniently situated service valves in each inlet supply MuST be fitted as an independent method of isolating the shower should maintenance or servicing be necessary.

f. If it is intended to operate the shower in areas of hard water (above 200 ppm temporary hardness), a scale inhibitor may have to be fitted. For advice on the scale inhibitor, please contact Customer Service.

g. DO nOT operate the shower outside the guidelines as laid out in ‘site requirements’.

Replacement parts can be ordered from Customer Service. See ‘spare parts’ for details and part numbers.

Water temperature requirements

Maximum hot water temperature = 80°C

Recommended maximum = 65°C

Minimum hot water temperature = 52°C

Maximum cold water temperature = 20°C

bS 6700 recommends that the temperature of stored water should never exceed 65°C.

A stored water temperature of 60°C is considered high enough to meet all normal requirements and will minimise the effects of scale in hard water areas.

Temperature adjustment rangeThe mixed water temperature can be adjusted from cold through to a top limit which can be preset during installation with full anti-scald protection throughout the range (35°C to 40°C), providing the hot water temperature at the inlet remains 10°C above the outlet temperature.

Should there be a loss of flow to either incoming supply then water from the shower will stop or be reduced to a trickle until both supplies are restored.

SITE REqUIREmENTSThe installation MuST be in accordance with Water Regulations and bylaws.

Minimum running water pressure: 0.5 bar.

Maximum running water pressure: 5 bar.

Maximum static water pressure: 10 bar.

For the best performance within the specified running pressure range a minimum flow of eight litres per minute should be available to both inlets.

While the mixer shower is operational (open outlet), inlet pressures MuST nOT be capable of exceeding 7 bar. For effective operation of the internal seals, the maximum static pressure must not be exceeded.

note: On sites where the running pressure is above 5 bar, the use of a suitably sized pressure reducing valve fitted in the cold mains supply pipework can provide nominally equal pressures at the mixer shower.

For best performance both the hot and cold water supplies to the mixer should be fed at nominally equal pressures.

The pipework should be installed such that the flow is not significantly affected by other taps and appliances being operated elsewhere on the premises.

note: Where thermal store systems and instantaneous gas water heaters are used, if excessive draw-offs take place the boiler may not be able to maintain an adequate output temperature. This could result in the shower temperature becoming noticeably cooler.

Fig.3 (diagrammatic view – not to scale)TYPICAl SUITABlE INSTAllATIONS

a) Instantaneous gas-heated systems, e.g. combination boilers (fig.3)

The shower control MuST be installed with a multipoint gas water heater or combination boiler of a fully modulating design (i.e. to maintain relatively stable hot water temperatures).

A drop tight pressure reducing valve MuST be fitted if the supply pressures exceed 5 bar running.

An expansion vessel (shown in fig.3) MuST be fitted, and regularly maintained, to make sure the shower mixer is not damaged by excess pressures. This may already be installed within the boiler (check with manufacturer) and is in addition to the normally larger central heating expansion vessel.

The layout and sizing of pipework MuST be such that nominally equal inlet supply pressures are achieved and the effects of other draw-offs are minimised.

The hot supply temperature MuST remain a minimum of 10°C hotter than the required blend temperature for optimum performance.

b) Unvented mains pressure systems (fig.4)

The shower control can be installed with an unvented, stored hot water cylinder.

For systems with no cold water take off after the appliance reducing valve, it will be necessary to fit an additional drop tight pressure reducing valve when the mains pressure is over 5 bar. The drop tight pressure reducing valve must be set at the same value as the unvented package pressure reducing valve.

note: An additional expansion vessel (fig.4) may be required if a second pressure reducing valve is installed. This does not apply to packages with a cold take off after the pressure reducing valve to the cylinder.

The layout and sizing of pipework MuST be such that nominally equal inlet supply pressures are achieved and the effects of other draw-offs are minimised.

c) mains pressurised thermal store systems (fig.5)

Packages of this type, fitted with a tempering valve (blender valve) can be used. A drop tight pressure reducing valve must be fitted if the supply pressures exceed 5 bar running.

An expansion vessel (shown in fig.5) MuST be fitted, and regularly maintained, to make sure the unit is not damaged by excess pressures. This may already be installed externally or internally within thermal store (check with thermal store manufacturer).

d) Pump assisted gravity fed systems (fig.6)The shower control MuST be fed from a cold water cistern and hot water cylinder providing nominally equal pressures.

The mixer unit may be used with a gravity fed system with a pump to boost pressures as shown.

Refer to the pump installation guide to establish the minimum head requirements for automatic operation of the pump.

INSTANTANEOUS WATER HEATERS APPlIANCE CAPABIlITIESFor the best performance from the shower when connected to an instantaneous water heater, the appliance MuST be capable of raising the temperature of the incoming water to a minimum of 52°C (125°F) and delivering a flow rate of not less than eight litres per minute.

The manufacturer recommends the fitting of straight connectors to allow flow limiters to be inserted into both valve inlets.

PREPARING THE mIXER VAlVECheck the contents to make sure all parts are present.

before installing, make sure all the openings on the valve are carefully covered to stop the ingress of any debris, etc. while routing the supply pipework.

The shower valve is suitable for installation on a solid wall, a stud partition wall, a dry lined wall or for fixing to a laminate cubicle or panel.

The hot and cold water pipes should be securely attached within the wall or panel to support the valve and prevent movement after installation.

The hot water inlet must be on the left-hand side as indicated in 'typical suitable installations'.

SITING OF THE SHOWER

Refer to fig.7 for correct siting of the shower.

Position the shower and showerhead on the wall so that all controls can be comfortably reached while using the shower. The showerhead can be positioned either side of the shower.

The unit must be positioned horizontally with the outlet port at the bottom.

Fig.7 (diagrammatic view – not to scale)

WarnInG!

the shower must not be positioned where it will be subject to freezing conditions.

ImportantConsideration must be given for the adequate

ceiling space for the installation of this shower. please see the dimensions shown

in fig.9.

INSTAllATIONDO nOT connect the outlet of the shower to anything other than the fittings supplied.

DO nOT use jointing compounds on any pipe fittings for the installation.

DO nOT solder fittings near the mixer unit as heat can transfer along the pipework and damage seals and thermostatic components.

note: Suitable service valves (complying with Water Regulations and bylaws) MuST be fitted on the hot and cold water supplies to the shower as an independent means of isolating the water supplies should maintenance or servicing be necessary.

note: To comply with Water Regulations and bylaws, if the showerhead can be placed within a bath, basin or shower tray, then a double check valve, or similar, must be fitted in the supply pipework to prevent back-flow.

When connecting the pipework, avoid using tight 90° elbows. Swept or formed bends will give the best performance.

The supply pipes can be routed either from the side, rising, rear or falling and must finish in suitable fittings (fig.8) to accept the offset connectors. When deciding on the location of the mixer valve, be sure to leave enough room for the riser/fixed head rail (fig.9).If installing into a stud partition or other hollow wall structures the installer will need to consider building rear supports or other options. Such options are beyond the scope of this guide.

The inlet centres on the mixer valve are 150 mm apart. However, the offset connectors give an extra 20 mm of adjustment.

The hot and cold supply pipes must be anchored rigidly in order to support the valve and prevent movement after installation.

Flush out the pipework in accordance with Water Regulations and Bylaws.Insert the check valves into the offset connectors (fig.�0). Make sure to fit the valves in the correct direction of flow.

Screw the offset connectors into the female elbows using PTFe thread tape, making sure the centres are correctly positioned for the mixer valve.

Screw the supplied collars onto the fittings until tight to the wall (fig.��). The collars will give a limited degree of tolerance and the amount of exposed thread will depend on the accuracy of the elbows set in the wall.

Offer the shower valve to the fittings and, making sure the sealing washers are in place, screw the unions onto the fittings.

FITTING THE RISER/FIXED HEAD RAIlMark the centre hole for the mounting bracket (fig.9) at a height of about 905 mm from the inlet datum.

note: The elongated hole in the mounting bracket allows for a small amount of adjustment.

Drill and plug the wall (the wall plugs provided are suitable for most brick walls — use an appropriate masonry drill, but if the wall is plasterboard or a soft building block, use suitable wall plugs and an appropriate drill bit).

Secure the bracket mounting plate to the wall (fig.��). Seat the upper part of the rail into the bracket, making sure the bracket engages the hexagonal fitting (fig.�3). using a suitable screwdriver, tighten the retaining screw to secure the rail to bracket. Screw the bottom part of the rail to the upper section and tighten.

While depressing the button on the handset holder (fig.�4), slide the holder onto the rail below the bracket.

Slide the base of the riser rail assembly into the opening in the diverter (fig.�5), then carefully locate the bracket holder onto the mounting plate (fig.�6). Secure in place by tightening the grub screw in the base of the bracket. Tighten the diverter collar, making sure the seal is in place.

Fitting the fixed showerheadScrew the fixed head (fig.�7) to the riser/fixed head rail. Make sure the sealing washer is in place and screw tight to seal the joint.Slider/holder

Fitting the hose and handsetConnect the one end of the flexible hose to the bottom outlet connector (fig.�8) on the diverter valve, making sure that the sealing washer is in place.

Screw the other end of the hose to the handset then locate the handset into the handset holder.

Important: It is the conical end of the hose which grips into the holder. The showerhead will not fit in the holder without the hose attached.

lEAk TESTINGFit the hose to the outlet and direct it to waste. Open the supplies and test for leaks in the valve connections. Remedy any leaks if necessary.

COmmISSIONINGMake sure that both the hot and cold water supplies are fully open and at (or near to) their design temperature and pressures and are within the requirements as stated.

Check the temperature knob (right-hand side) is rotated fully anti-clockwise (press the override button to achieve maximum temperature setting).

Make sure the showerhead is directed to waste.

Start the water flow by turning the flow control (left-hand side) anti-clockwise.

Allow the shower to run at the maximum temperature setting until the water temperature has stabilised. Rotate the temperature control knob until your desired maximum showering temperature is reached.

The mixer valve is fitted with a maximum temperature override button.

The mixer valve is factory set to give a maximum outlet temperature of 38°C. For the user's safety this should be checked on site to make sure the setting has not been altered.

OPERATING THE SHOWERThe controls for the mixer shower are shown in fig.�9.

To start the shower, rotate the On/Off flow control (left-hand side) fully anti-clockwise for maximum flow.

To stop the water flow, rotate the On/Off flow control fully clockwise.

To adjust the water temperature, rotate the temperature control (right-hand side) — clockwise for a cooler shower or anti-clockwise for a hotter shower.

To overcome the maximum temperature stop, depress the red temperature override button.

CautIon: Exposed metal surfaces may become hot during use.

Adjusting the maximum temperature override setting

Remove the end cap from the temperature control knob to expose the retaining screw (fig.�0). undo the screw and pull off the knob.

Turn the flow control (left-hand control) clockwise and allow the shower to run until the water temperature has stabilised.

Carefully turn the temperature spindle anti-clockwise to increase the maximum outlet temperature (fig.��). Once you are satisfied with the showering temperature refit the temperature control. Take care to align the override button with the white marker on the maximum temperature stop (fig.��).Secure the temperature control in place with the retaining screw and refit the end cap.
